SSAW STEEL PIPE

SSAW pipe, or spiral seam submerged arc welded steel pipe, is made from coiled steel. After uncoiling, flattening, and edge milling, it is gradually rolled into a spiral shape using a forming machine. The internal and external seams are welded using an automatic double-wire, double-sided submerged arc welding process. The pipe then undergoes cutting, visual inspection, and hydrostatic testing.

LSAW STEEL PIPE

LSAW STEEL PIPE (Longitudinally Submerged Arc Welding Pipe) is a straight seam submerged arc welded pipe. It uses medium and thick plates as raw materials. It is pressed (rolled) into a pipe blank in a mold or forming machine, and then double-sided submerged arc welding is used to expand the diameter.

Application

LSAW steel pipes are widely used in many fields. In the energy industry, they are the core material for oil and natural gas pipelines, and are especially suitable for oil and gas transportation in Class 1 and Class 2 areas such as high-altitude and submarine areas. In construction projects, they can be used for natural gas pipelines and scaffolding structures, as structural columns, and as key components such as piers, towers and beams in bridge construction. In the field of mechanical manufacturing, they can be used to manufacture precision pipes for components such as automobile chassis and exhaust pipes, as well as to produce pressure pipes and pressure vessels for transporting high-temperature steam and high-pressure liquids. At the same time, it is also widely used in other fields such as chemical industry, water conservancy and marine engineering.

ERW STEEL PIPE

ERW (Electric Resistance Welded) steel pipe is a type of steel pipe made by heating the edges of steel strips (or plates) to a molten state using resistance heat generated by high- or low-frequency currents, followed by extrusion and welding using pressure rollers. Due to its high production efficiency, low cost, and wide range of specifications, it has become one of the most widely used types of steel pipe worldwide, serving a wide range of industries, including oil and gas, water supply and drainage, and machinery manufacturing.
